Mitch the Enchanted Rhinoceros

Mitch the Enchanted Rhinoceros is a caretaker of the Easter bunnies and chickens in the episode "June's Egg-cellent Adventure: Juniper Lee Meets the Easter Bunny". He went rogue after tiring of looking after them and sought to take over the Easter holiday, his plan being to cause a war between the bunnies and chickens and then replacing eggs with batteries and socks.
Despite escaping Juniper and the Easter moms as well as continuing with his plan, it ends up failing miserably.
